Submission + - SPAM: Credit card has display, acts as security token

Bearhouse writes: From the BBC:

A credit card with an LCD display and built-in keyboard has been launched in Singapore by Mastercard.

The card has touch-sensitive buttons and the ability to create a "one-time password" — doing away with the need for a separate device sometimes needed to log in to online banking.

"We brainstormed on ways to make it convenient and yet secure for customers," said V Subba from Standard Chartered Bank, which is collaborating with Mastercard.

"The question was: instead of sending customers another bulky token, could we replace something which already exists in the customer's wallet?"

Sounds convenient but perhaps less secure than having a separate device...I also wonder how robust it will be?
